最后，根据轨道衰减的影响，它开始播在地球表面的遗体。
Eventually, under the influence of orbital decay, it began to strew its remains across the Earth's surface.
这样就改变了GPS信号的传播，减小了地球底层轨道上空间碎块的衰减速度。
This altered the propagation of GPS signals and slowed the rate of decay of space debris in low Earth orbit.
轨道会渐渐衰减，这是因为卫星与为数甚少的空气分子之间相互碰撞所致。即使是在通常被划归为“外太空”的高度上也还找的到这些分子。
Orbits gradually decay as a result of collisions with the small number of air molecules found even at altitudes normally classified as "outer space".
